Abstract

4,4-diaryl-3-ethoxycarbonyl-3-butenoic acid (2a-d, Scheme 1) has been synthesized by Stobbe condensation of substituted benzophenones 1a-d with t-potassium butoxide and diethyl succinate. Compounds 2a-d on reduction with sodium amalgum furnished 4,4-diaryl-3-ethoxycarbonyl-3-butanoic acid 3a-d, which on intramolecular cyclization with polyphosphoric acid gave target compounds 4-aryl-3-ethoxycarbonyl-1-oxo--1,2,3,4-tetrahydronaphthalene 4a-d.
